i 16 claims. (ci. 15z4) This invention relates to polishing devices and,more particularly, to an improved manually controlled and portable powerdriven polishing tool of the rotary type.

It is an object of this invention to provide a polishing device of thecharacter described which is particularly devised for polishing shoesand comprises a portable frame whose lower end is provided with anannular rotary polishing brush or pad and an inner axially movablereservoir or housing for containing wax or a paste type of polishingcompound with a polish applying brush journaled on the lower portion ofsaid inner housing about an axis substantially transverse to the axis ofthe polishing brush. Means are provided to shift the inner housingaxially of the outer polishing brush so the polish applying brush orapplicator element is lretractable and extensible with respect vto theouter polishing brush and wherein means are provided to automaticallytransmit rotation to the polish applying brush or applicator elementonlywhen it is in extended position.

When the applicator element is driven, its bristles or other surface,remote from the surface to which the polishing compound is to beapplied, rub against the paste wax orcompound so that some of thecompound adheres to the applicator element and is, thus, transferredonto the surface to be polished. Thus, when the inner polishing elementor annular brush is retracted relative to the outer polishing element orannular brush, the outer polishing element then polishes the desiredsurface by a rotary motion without applying additional polishingcompound to the surface.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings, in which:

Figure l2 is a fragmentary sectional plan view taken substantially alongline 12-12 in Figure 1l.

Referring more specically to the drawings, the iirst form of theinvention is shown in Figures 1 through 10 and, for purposes of clarity,it will -be assumed that the polishing tool normally occupies theposition shown in Figure 1 although it is apparent that the polishingtool may be used in any desired attitude. The polishing tool comprises amain housing broadly designated at 10 which is shown in the form of acylindrical shell, but which may be of any desired construction.

The lower portion of the main housing 10 has an annular shoulder orbearing member 11 therein which may be integral with the housing 10 ormay be in the form of a ring secured in the housing 10, as by screws 12,Spaced above the annular bearing 11 is a pair of diametrically opposedarcuate or segmental blocks 13, 14 which may also be integral with thehousing 10` and are shown as being xed to the housing as by screws 151,16. The screws 15`also serve to secure a guide block 20 to what may betermed as the rear surface of the shelllike housing 10.

A drum-like axle or outer rotary element 21 is loosely mounted in thehousing 10 and is provided with a reduced journal portion 22 whichextends through and is journaled inthe annular bearing member 11. Theupper end surface of the axle 21 of the iirst form of the invention issmooth and spaced below the level of the blocks 13, 14 for engagement bya driving roller 23, preferably made of rubber or other resilient orfriction material. It will be observed in Figures 5, 6 and 7 rthat thelower outer portion ofthebloclr 13 is cut away to form an opening 25therein to accommodate the friction lroller 23. Also, the external block20 and the housing .10 are provided with coinciding passageways oropenings26 through which the roller`23 loosely extends.v The roller 23is xed on a shaft 27 which may be a part of an electric motor, such asis indicated at 30 in Figures l, 2 and 3, or which `may be connected toa ilexible shaft driven by a motor or other means remote from theimproved polishing apparatus. A shaft of this type is shown inassociation with the modied or second form of the invention to be laterdescribed.

ln this instance, the electric motor 30 is provided with a reduced frontend portion 31 which tits in a pressure block 32 guided for verticalmovement in the external guide block 20. The pressure block 32 islimited as to vertical movement by a pair of vertically spaced retainingblocks 33, 34 fixed in the external guide block Ztl. Opposed sides ofthe external guide block 20 are provided with slotsV 35 therein toprovide access to a pair of screws 36 which are threaded intooppositesides of the pressure block 32 and bear against opposite sides of thereduced portion 31 of the electric motor 30 to securel said reducedportion in the pressure block y32.

`rEhe lower retainingblock34 (Figure 5) has ashaft 40 mounted forsliding movement therein parallel to the axis of the housingland whoseuppery end,` is suitably s ecuredto the pressure block 32, as bybeingthreaded 'thereinto- |lfhe lowerretaining blockS-l has a cavity 41iii its lower portion through which the shaft 40 extends and in whichthe upper portion of a compression spring 42 is positioned. The lowerend of compression spring 42 bears against an abutment 43 on the lowerend of the shaft 40, which abutment is shown in the form of a Washersupported on the lower end of the shaft 40 by means of a lock nut 44.

It is thus seen that the pressure block 32 is normally urged downwardlyso the motor 30, shaft 27 and roller 23 are urged downwardly therewithrelative to the housing and thereby insures that the roller 23 ismaintained in pressure engagement with the mating or upper end surfaceof the axle 21. It is thus seen that, when the motor is energized, theroller 23 transmits rotation to the axle 21.

The lower end of the reduced portion 22 of the axle 21 has an annularouter polishing element support ring 46 mounted thereon preferably bymeans of a plurality of circularly spaced radially and inwardlyprojecting pins 47 which iit in corresponding bayonet slots 50 providedin the lower end of the reduced portion 22 of the axle 21. The element46 may also be termed as an outer annular brush holder. This brushholder is preferably channelshaped in cross-section and in this instancethe metal encased upper end of an annular brush 52 is xed in the brushholder 46 by means of the pins 47. It is to be distinctly understoodthat a pad or other annular resilient polishing element may besubstituted for the brush 52, without departing from the spirit of theinvention.

Mounted for axial movement within the main housing 10 is an elongatedtubular secondary or inner housing broadly designated at 55. The upperportion of the inner housing 55 is loosely mounted for movement betweenthe proximal surfaces of the inner guide blocks 13, 14 and these guideblocks have the upper portions of respective keys or guide rods 56, 57suitably secured thereto, which guide rods extend downwardly andterminate within and adjacent the lower end of the reduced` portion 22of the axle 21. The inner tubular housing 55 is guided for axial orvertical sliding movement on the keys 56, 57 as best shown in Figures 7and 8.

The inner or secondary housing 55 has a longitudinally extending,eccentric and internally threaded bore 60 therethrough within which atubular polishing compound cartridge holder or reservoir 61 is looselymounted. It should be noted that the tubular reservoir 61 is notexternally threaded. Instead, a polishing stick cap 62 is mounted foraxial sliding movement in the polishing stick holder 61 and has a key orpin 63 projecting radially and outwardly therefrom through alongitudinally extending slot 64 provided in one side of the polishingstick holder 6l (Figures 7, 8 and 9). The outer end of the pin or key 63engages the threads in the threaded bore 60 of the inner housing 55, forpurposes to be later described.

The cap 62 is preferably of inverted cup-shaped construction and isprovided with a key 66 therein for attaching the upper end of apolishing stick 67 to the cap 62. The polishing stick 67 may be madefromwax or any other desired pliable polishing material and is of suchdiameter to move freely and axially within the polishing stick holder61.

The tubular polishing stick holder 61 projects above the level of theblocks 13, 14 and has an enlarged head member 70 integral therewith orattached thereto and provided with an annular groove 71 in its peripherywhich is engaged by the free end of a latch 72. The latch 72 is fixed onthe upper end of a relatively small rod or shaft 73 (Figures 6, 7, 8 andl0) whose lower end is journaled in the inner housing 55 and extendsthrough a groove or notch 74 formed in the periphery of the upperportion of the housing 55. A collar 75 is fixed on a medial portion ofthe shaft 73 or formed integral therewith and is positionedin the notch74. The lower end of the collar 75 is provided with a notch 76for'accomrnodating a torsion spring 77 (Figure 10) encircling the shaft73.

One end of the torsion spring engages the shoulder formed by the notch76 in the collar 75 and the other end of the torsion spring 77 engagesthe inner wall of the notch or groove 74 to thereby normally urge thelatch into operative position as shown in Figure 8. It will be notedthat latch 72 is held on the upper end of the shaft or rod 73 by meansof a pin 80 (Figure 8) which serves as a hand lever for swinging thelatch 72 out of engagement with the groove 71 in the cap 70 of thepolishing stick holder 61 so the polishing stick holder may be readilyremoved from the inner housing 55, when desired.

It will be noted in Figures 6, 7, 9 and 10 that the outer surface of theinner housing 5S is also provided with a pair of adjacent recesses 81,82. The shaft 73 also extends through the recess 81 and has a sleeve 83loosely mounted thereon and loosely positioned in the recess 81. Theinner surface of the sleeve 83 is attened, as at 84 (Figure 7) toprevent inadvertent rotation of the sleeve 83. The sleeve 83 has aradially projecting pivot pin 85 tixed thereto which ts in thebifurcated forward end of an operating lever 86 (Figure l0).

The operating lever 86 curves rearwardly inwardly of the wall of thehousing 10 and then extends outwardly through an opening 87 formed inthe cylindrical shell of the housing 10. The operating lever 86 ispivoted, as at 90, adjacent its rear or outer end, on a plate 91suitably secured to one side of the external guide block 20. The plate91 could be omitted, but it is provided to cover the recess in which thehead of the corresponding screw 1S is disposed.

The upper portion of the operating lever 86 may extend rearwardly andterminate adjacent the motor 30 so as to be manually operated, ifdesired. However, for convenience, the upper portion of the externalguide block 20 has a projection 92 on one side thereof in which a pairof push buttons 93, 94 is mounted for vertical sliding movement. Thelower ends of the push buttons 93, 94 are pivotally connected, as at 9S,96 to the operating lever 86 rearwardly and forwardly of the pivot 90,respectively.

It isthus seen that, when the inner housing 55 is in raised positionrelative to the outer housing 10 as shown in Figure 10, the forward pushbutton 94 may be depressed to lower the housing 5S to substantially theposition shown in Figures 1, 5 and 6, for example. On the other hand,when the rear push button 93 is depressed, the inner housing 5S isretracted from the position shown in Figures l, 5, 6, 9 and ll to theposition shown in Figure l0. In order to assist in maintaining the innerhousing S5 in the position to which it is moved by either of the pushbuttons 93, 94, a retaining latch 97 is pivotally connected to theoperating lever 86 (Figures 1 and l0) adjacent the pivot 96 of the pushbutton 94. This latch 97 extends downwardly and rearwardly at an angleand has a pair of closely spaced recesses or notches a, b in its rearedge which are adapted to alternately engage a retaining pin cprojecting outwardly from the plate 91.

A leaf spring member or torsion spring d is mounted on a pin eprojecting from the plate 91 and bears against the lower forward surfaceof the retaining latch 97 to thereby urge the retaining latch 97 intoengagement with the retaining pin c. When the inner housing 55 is in theretracted position shown in Figure 10, the notch a engages the retainingpin c and, when the inner housing 55 is in extended position relative tothe outer housing 10, the notch b in the retaining latch 97 engages theretaining pm c.

As heretofore stated, the threaded bore 60 in the inner housing 55 iseccentric relative to the axis of the inner and outer housings 55, 10and it' will be observed in Figures 1, 3, 4, 6 and 9 that the innerIhousing 55 is provided with a pair of downwardly projecting ears oriins 100, 101 which are substantially alined with substantiallydiametrically opposed inner surfaces of the threaded bore 60 and betweenwhich a rotary inner polishing element or applicator 102 is mounted forrotation about a substantially horizontal axis, or, in other words,about assaess an axis transverse to the axis of the outer rotary polishing element 52.

In this instance, the inner rotary polishing element 102 is shown in theform of a brush whose bristles rub against the lower end of thepolishing stick 67 disposed in the polishing stick holder 61, as bestshown in Figures 5 and 9. As best shown in Figure 4, the core of thebrush 102 is fixed on a shaft 104, one end of which is journaled in abushing 105 threaded through the ear 100 extending downwardly from theinner housing 55. It will be noted that the lower end of the ear 100 hasa slot 106 therein (Figure 5) which communicates with the threaded bore60 through which the bearing or bushing 105 extends and which is ofsufficient width to permit the shaft 104 to pass therethrough.

The end of the core of the brush 102 opposite from the bushing 105 has ahub portion 107 projecting therefrom (Figure 4) and the outer end of alateral key portion f on the right-hand end of the shaft 104 in Figure 4terminates substantially flush with the outer surface of the hub 107.The ear or iin 101 projecting downwardly from the lower end of the innerhousing 55 has a stub shaft 110 journaled therein which stub shaft isalso journaled in an auxiliary fin or ear 111 which also depends fromthe inner housing 55 and is spaced outwardly of the fin or ear 101. Theinner end of the shaft 110 is slotted to engage the key f on thecorresponding end of the shaft 104 and it will be noted that the innerend of the stub shaft 110 then fits in the hub 107.

It is thus seen that, by removing the bushing 105 from the iin 100 inFigure 4, the brush 102 with its shaft 104 may be moved to the left todisengage the key f from the corresponding end of the stub shaft 110 andto thereby facilitate ready removal of the brush 102 from between thefins 100, 101 of the inner housing 55 for purposes of cleaning orreplacement, if desired.

Now, in order to drive the lateral brush 102, the shaft 110 has arelatively small worm gear 112 fixed thereon which engages a worm 113(Figures l, 3, 6 and 9) mounted on the lower end of a shaft 114 whichextends parallel to the axis of the outer and inner housings 10, 55. Theshaft 114 is journaled in the wall of the inner housing 55 and extendsthrough the recess 82, the latter recess being of substantially greaterlength axially of the inner housing 55 than the recess 83. Disposedwithin the recess S2, of the housing 55 is a resilient or pliable roller115 which is fixed to or molded onto a bushing 116, mounted for axialsliding movement on the shaft 114.

rllhe shaft 114 is slotted longitudinally thereof, as at 117 (Figures 6and 7), and a pin 120 (Figure 9) loosely extends through the slot 117and is fixed in the bushing 116 and the roller 115. Thus, the roller 115is keyed for axial movement on the shaft 114, but cannot rotate relativeto the shaft 114. The upper end of rolle-r 115 is engaged by the lowerend of a co-mpression spring 122 whose upper end bears against the upperwall of the recess 82 as best shown in Figure 9. The shaft 114 has acollar 123 adjustably secured thereon for engaging the bottom wall ofthe recess 82 to thereby prevent endwise movement of the shaft 114relative to the inner housing 55.

The lower portion, at least, of the roller 115 is preferably tapered asshown in Figure 9 and, when the inner housing 55 is moved to extendedposition from, say, the position shown in Figure l0 to that shown inFigures 5, 6 and 9, the roller 115 engages a tapered inner surface 124on the tubular axle 21. Since the tubular axle 21 is constantly drivenin the manner heretofore described, it is apparent that, when the roller115 is moved downwardly into engagement with the tapered surface 124 ofthe axle 21, and biased thereagainst by the compres sion spring 122,rotation is then imparted to the shaft 114, which, in turn, drives thelateral brush 102 through the medium of the worm 113, worm gear `112,shaft 0 and the shaft 104 of the inner rotary polishing element 102.

Itis thus seen that means are provided to automatically impart rotationto the secondary or polish applying brush 102 whenever it is in extendedposition relative to the outer rotary element or brush 52 and to alsoautomatically cause rotation of the inner polishing element orapplicator 102 to cease when it is in retracted position relative to theouter rotary polishing element 52.

Since the inner brush 102 rubs against the lower end of the polish stick67 during rotation thereof, it is apparent that the inner brush 102transmits polish from the polish stick 67 to the surface to be polished.On the other hand, when the inner brush 102 is retracted, since theouter brush 52 rotates continuously, it is apparent that the surface tobe polished may then be polished without additional polishing compoundbeing applied thereto. i

Now, the polish stick 67 may actually be of greater length than thatshown in Figure 5 when it is initially inserted in the polish stickholder 61. On the other hand, as the polish stick is used, it isapparent that it becomes worn and it is necessary to extend the samerelative to the polish stick holder 61. However, it is necessary, inorder to move the polish stick 67 in either direction, for the operatorto grasp the head 70 of the polish stick holder 61 to thereby rotateboth the head 70 and the polish stick holder. In so doing, the pin 63causes the polish stick cap 62 and polish stick 67 to rotate with thepolish stick holder 61 and it is apparent that the pin 63 follows thethreads in the threaded bore 60 so that, with rotation of the polishstick holder 61 in one direction, the polish stick 67 and cap 62 aremoved axially in one direction and, conversely, with rotation of thepolish stick holder 61 in the other direction, the polish stick 67 andthe cap 62 move axially in the other direction.

It might be stated that, in order to remove the polish stick holder 61from the housing 55, it is necessary to rotate the same until the pin 63has moved the polish stick 67 and the cap 62 to where the pin 63 isdisposed above or has ridden out of engagement with the threads in thethreaded bore 60. The upper end of the main housing 10 is partiallyclosed by a dome-like closure cap 130 whose upper end is preferablyprovided with an opening 131 therein so that the operator may View theposition of the polish stick cap 62 therethrough Without removing thecover or closure cap 130.

The polish stick holder 61 may also be rotated by inserting ones fingersthrough the opening 131. The lower end of the closure cap preferablyfits within the cylindrical shell forming the main housing 10 and isprovided with bayonet slots 132 for engaging pins 133 projectinginwardly from the main housing 10 to thereby facilitate easy removal ofand replacement of the closure cap 130, when desired.

Referring now to the form of the invention shown in Figures ll and 12,most of the parts shown in Figures l1 and 12 may be identical to orsubstantially the same as corresponding parts shown in Figures l throughl0 and, accordingly, the same reference characters will apply in orderto avoid repetitive description. In the form of the invention shown inFigures ll and l2. instead of an electric motor being used as the motivemeans for the polishing tool, an adapter lits in the pressure block 32and is secured therein in the same manner as the reduced portion 31 ofthe electric motor 30 is secured in the pressure block 32 in the firstform of the invention.

The adapter 140 has the housing 141 of a flexible shaft 142 connectedthereto, the other end of the housing 141 and exible shaft 142 beingconnected to a suitable motor or other driving means remote from theimproved polishing tool. The inner end of the iiexible shaft 142A has abevel gear 144 fixed thereon which is used in the form of the inventionshown in Figures l1 and l2 in place of the resilient roller 23 used inthe first form of the invention. Accordingly, the upper end surface ofthe axle 21 in Figures 1l and 12 is provided with gear teeth 145 whichare engaged by the bevel gear 144 so that rotation is imparted to theaxle 21 in Figures l1 and 12 through the medium of gears rather than byfrictional contact between the driving and the driven elements as shownin Figures and 7.

It will also be noted that, whereas in the original or first form of theinvention, the resilient roller 115 is used for transmitting rotationfrom the axle 21 to the vertical shaft 114, in the modified form ofpolishing tool (Figures 11 and 12) a bevel gear 150 is substituted forthe resilient roller 115 and the upper portion of the axle is providedwith an inner tapered surface formed with gear teeth 151 which areadapted to be engaged by the gear 150 when the inner polishing elementor lateral brush 102 is in extended position. In all other respects, theform of polishing tool in Figures ll and 12 is identical to the form ofpolishing tool shown in Figures 1 through and a further detaileddescription thereof is thus deemed unnecessary.

It is thus seen that I have provided a novel polishing tool particularlyadapted for use with a plastic or semiuid type of polishing compoundwith means for continuously rotating the outer annular brush orpolishing element 52 and means for extending and retracting the innerpolishing element or applicator 102 relative to the outer polishingelement or brush 52 and wherein the inner polishing element is driven torotate about an axis transverse to the axis of the outer polishingelement or brush 52.

In the drawings and specification there have been set forth preferredembodiments of the invention and, although speciic terms are employed,they are used in a generic and descriptive sense only and not forpurposes of limitation, the scope of the invention being deiined in theclaims.
